Bring your coding agents and friends. Import your harnesses and fly them in parallel from desktop, web, or phone.

Supaplane is a multi-surface workbench for coding agents. Bring Claude Code, Codex, OpenCode, Cursor, and friends. Import the harnesses you already use, get back to speed, and run them in parallel from desk, browser, or phone.
A single supervised daemon owns agent lifecycle, worktrees, and remote access. Surfaces are thin clients over that daemon, not separate apps fighting for the same repo.
Formerly Spanner (née Pidex, née OpenPi). Personal project under echohello. Companion installer: hoist.
| Local / self-hosted | Multi-vendor | Multi-surface | Open source | |
|---|---|---|---|---|
| T3 Code | yes | yes | web / desktop | MIT |
| Paseo | yes | yes | desk + phone | AGPL |
| Conductor | yes (Mac) | yes | desktop | closed |
| Superconductor | cloud-first | yes | desk + mobile + Slack | closed |
| OpenChamber | yes | OpenCode-first | desk + web + phone | MIT |
| Supaplane | yes (daemon you control) | yes | desk + web + phone | MIT |
The open lane is local control, any harness, every surface. That is the runway we are on.
| Surface | Package | Role |
|---|---|---|
| Desktop | @echohello/desktop | Electron shell that spawns and supervises the daemon |
| PWA / web | @echohello/web | Vite + React renderer; works on the relay too |
| Mobile | @echohello/app | Expo / React Native companion |
| CLI | @echohello/cli | supaplane commands for daemon, agent, provider, worktree |
Greenfield scaffold. Expect rough edges.

- OpenCode (
@opencode-ai/sdk) - first provider - Cursor (
@agentclientprotocol/sdk) - proves the ACP path - Claude Code (
@anthropic-ai/claude-agent-sdk) - MCP server (
@modelcontextprotocol/sdk) for agent-to-agent work - Codex, Copilot, Pi/OMP - later, Paseo parity
See docs/providers.md.
Alpha scaffold. Daemon, protocol, client, and surface stubs are in place. CI runs on every PR; calver YYYY.MM.DD[-N] release tags are stamped on every push to main. Architecture decisions live in docs/ and the build-research notes that fed this repo.

Made to fly with open harnesses and a daemon you own.
